We basically solved our coffee crisis by carrying coffee, travel mugs and a sieve with us at all times. Then, all we have to do is ask for hot water. It works like a charm. We have made coffee on many roadsides, but we always have it the way we like it. I definitely understand this one!
The other one that I would agree with is dryers. We have definitely packed up wet clothes in our suitcases on more than one occasion.
Driving is fun but I don't really miss it. Especially not in countries where there are terrible drivers.
